Hi,

Hi,

It seems like all the data is received, but the meter sends an invalid HDLC status byte.
7E A8 7E... should be
7E A0 7E...

Dear Sir,

Dear Sir,
Thanks!!! Its working now.

Negotiated Max PDU size should be less than negotiated server max TX RX lenght in SNRM UA

Hi,

Hi,

If Negotiated Max PDU must be smaller than the maximum frame size in SNRM UA then the PDU must fit to one frame. That is not a problem if you have a lot of RAM.
